I am not able to boot my Power Mac 7,3 with the Ubuntu MATE 16.04 daily-live iso.

This has been the case since the 4.3.x kernel series and is now with current 4.4.x kernel. At the time the 4.2.x kernel was used booting the iso went fine!

During the boot-process I get following error messages:

"Problem Loading in-kernel X.509 Certificate (-74)"
[...]
mount: mounting /dev/sda10 on /cdrom failed: no such device
stdin: not a typewriter
mount: mounting /dev/sda9 on /cdrom failed: no such device
mount: mounting /dev/sr0 on /cdrom failed: no such device
[...]
(initramfs) unable to find a medium containing a live file system

The stdin: and mount: lines get repeated several 10 time. At last the boot process stops wuth the (initramfs) line, dropping me in a busybox shell.
